The betrothed couple enjoyed their holiday weekend by cozying up and taking in some tennis action at the 2014 U.S. Open in New York City.

The lovebirds displayed some sweet PDA while watching Victoria Azarenka win her match at the USTA Billie Jean King Tennis Center. The 28-year-old designer, who kept it simple in a white tee and aviators, casually rested her arms on her French billionaire beau's shoulder as they snuggled close in their seats.

The PDA-friendly pair was also caught cuddling at a charity event in the Hamptons several weeks ago. The two attended the Paddle & Party for Pink benefitting the Breast Cancer Research Foundation and were joined by the fashion mogul's twin sis, Ashley Olsen.

"They were very lovey-dovey, a lot of PDA," an eyewitness said. "Nothing inappropriate, but very affectionate. She and Olivier were in high spirits, laughing and chatting with Ashley."
